AXLE-=BEARING' FOR STRAINERS.

SPECIFICATION forming part of Letters Patent No. 735,411, dated August 4, 1903.

Application filed February 4,1903. Serial No. 141 ,914. (No model.)

. To ttZZ whom it may concern.-

Be it known that I, PAUL REINIOKE, a subject of the Duke of Anhalt, residing at K6 then, in the Duchy of Anhalt, German. Empire, have invented a new and Improved Axle- Bearing for Strainers, of which the following is a specification.

This invention relates to an axle-bearing for strainers in which a packing of india-rubber and metal is arranged between the axlebox and the beating-wings.

Ihave represented one form of construction of my improved axle-bearing in the accompanying drawing, in which is shown the hearing portion of a strainer box, partly in side view and partly in section.

The object of my invention is to pack the axle of the beating-wings where it passes nected with a cylindricalprojection a of the strainer box or casing 70 by threaded bolts 8 and by nuts located on both sides of the flange, said projection forming the bearing portion of the strainer or its box. Between the axle-box b and the nave m the axle 0c is provided with the elastic ring g, consisting of india-rubber or the like,and with the metal ring '5. These rings may be compressed between the parts b and m by means of the bolts .9 and their nuts. I prefer to shape the neighboring surfaces of the rings g and t in such a manner that the oscillatory movements of the ring g, which embraces the axleoc tightly, are transmitted to the metal ring 11, so as to move the same in the same manner. In the form of construction shown the ring t' is funnelshaped and the ring g forms a truncated cone, the neighboring inclinations being perfectly the same.

The outer end of the axle a: carries a crank r, by means of which an oscillatory motion is imparted to said axle, and as the nave m of the beating-wings Zis fixed to the axle the pulp is forced through the slotted plate 19. The rings 9 andt' oscillate in just the same manner as the axle 0c, and a slight friction arises only between the metal ring 2' and the axle-box b. The surfaces of contact of the parts '6 and b are but small,and there is no dilficulty in making them exactly fit one to the other. The pulp is perfectly prevented from entering between the axle so and the axlebox b, so that the movement of the axle is not in the least impeded. Pulp may enter, it is true, between the axlebox Z and the bearing a; butno damage can herefrom arise because there is no relative motionfbetween the two parts in question.

' It is obvious that care need be taken only with respect to the surfaces of contact of the parts iand I), because that is the only place where pulp'could possibly enter between the axle a; and axle-box b.

The nave m might be replaced by a ring or a sleeve, and the rings g and 1} need not con sist each of one part; but they might consist of two or more parts and there might be more rings than only two, this being in every case immaterial for the subject-matter of the invention.

Having now described my invention, what I desire to secure by a patent of the United States isr 1. In a pulp-strainer, the combination of the casing a, a casing b fitting within the same but having no relative movement thereto, an axle, beating-wings thereon, and rings on the axle between the casing b and the beatingwings.

2. In a pulp-strainer, the combination of the casing 00, a casing 12 fitting within the same and having no relative movement thereto, an axle, beating wings thereon, a metal ring bearing against the inner face of the casing b, and a rubber ring carried by the axle, hearing against the metal ring and means for holding the rubber ring in position.

3. In a pulp-strainer, the combination of a casing to, a casing b therein, an axle, a metal ring bearing against the inner face of the casing b, and having its other end beveled inwardly, a rubber ring carried by the axle and having a cone-shaped portion engaging the beveled part of the metal ring.

Patented August 4, 1903.

4. In a pulp-strainer, the combination of a engaging the flange and nuts on the bolts to lo casing a, a casingb therein, an axle, a metal adjust the pressure of the rings. ring bearing against the inner face of the In witness whereof I have hereunto set my casing b and having its other end beveled in- I hand in presence of two witnesses. wardly, a rubber ring carried by the axle and having a cone-shaped portion engaging the I PAUL REINIOKE beveled part of the metal ring, and means Witnesses: for pressing the rings together consisting of RUDOLPH FRIOKE, a flange on the casing 1), bolts on the casing EMIL ZIEGER.
